Hoisting device for ship pipeline

Abstract

The invention provides a hoisting device for a ship pipeline. A crossbeam is provided with a first hanging rod and a second hanging rod. The lower end of the first hanging rod is connected with a bracket. The bracket is provided with a circular ring with the same curvature radius with the bracket. The circular ring is divided into a first half circular ring and a second half circular ring. The pipeline is placed in the circular ring. A gasket is arranged between the contact points of the inner wall of the bracket and the outer wall of the first half circular ring. The second half circular ringis provided with a supporting frame connected with the first hanging rod. A positioning nut is arranged between the supporting frame and the first hanging rod. An elastic piece is arranged between the positioning nut and the supporting frame. The lower end of the second hanging rod is connected with a protective bracket. The hoisting device for the ship pipeline has the beneficial effects that agap between the hoisting device and the pipeline is reduced through the U-shaped bracket, a certain space of expansion and contraction of the pipeline is further arranged, the half circular rings arearranged obliquely upwards, the elastic piece, the gasket and a buffering piece can conduct compensating on expansion of the pipeline, the protective bracket plays a role of protecting the pipeline, and safety of the pipeline is improved.

Description

technical field [0001] The invention belongs to the technical field of ship machinery and equipment, and in particular relates to a hoisting device for ship pipelines. Background technique [0002] Pipelines in ships need hangers fixed on the hull components to prevent pipes from sagging, deflecting, shaking, etc., because to prevent damage to pipelines or damage to the tightness of pipeline joints. The double-row pipe hanger wraps the support and the double-row semi-circular ring, the semi-circular ring is fixed on the support by means of the connector, the pipeline is installed in the semi-circular ring, and the support is fixed on the hull. At present, there is a large gap between the semi-circular ring of the double-row pipe hanger and the pipe with digital display on the market. Due to the large vibration when the ship is sailing, the vibration of the pipe in the semi-circular ring cannot be avoided, and the large gap will produce a strong impact. It is easy to cause d...

Problems solved by technology

At present, there is a large gap between the semi-circular ring of the double-row pipe hanger and the pipe with digital display on the market. Due to the large vibration when the ship is sailing, the vibration of the pipe in the semi-circular ring cannot be avoided, and the large gap will produce a strong impact. It is easy to cause damage to the hanger or the pipeline, and there is no compensation device on the hanger. When the pipeline is thermally expanded, it will cause the pipeline to rupture. The risk factor is high and it will cause a safety accident.
